Exclude Layer from Legend Widget

Hi there,

Does anyone happen to know if there is currently a way to exclude specific layers from the Legend Widget?

Regards,

Michael

I believe the best way to exclude a layer is in the Arcgis online map.

What ever legend is used in that map will display in the legend widget.

Rickey,

For Web appbuilder that method does not work for me. I still get items in my legend widget that I hid in AGOL.

When I use a Web Map from ArcGIS Online then this does work for me.

Stan, I am not sure why yours is not working but it should.

However, I am testing out the Local Layer Widget so my layers are coming from my ArcGIS Server not AGOL.

As far as I can tell there currently seems to be no way to exclude layers from the Legend when using Local Layers.

If anyone has any suggestions that would be greatly appreciated.

Regards,

Michael

Michael,

Would excluding it from the LayerList widget and the Legend widget work for you or are you just wanting to remove it from the Legend?

Hi Robert,

I would like to have it shown on the map but I do not want it in the Legend.

Michael

Michael,

I have an enhancement in mind for the Local Layer Widget but it would hide the layer from the Layer List Widget as well as the Legend widget. That would mean that you could not turn the layer on or off at runtime due to it not appearing in the Layer List widget.

Michael,

My layers are coming from our ArgGIS Server to AGOL and being used in WAB Developers edition.

If I go into the AGOL web map and hide the layer in the legend(as mentioned above), but still have the layer turned on then in WAB when the layer is turned on it shows up in the legend. To me it seems that WAB does not respect the setting in AGOL to hide items in the legend.

Stan,

That is strange as there is definitely code in the Legend widget to handle the "showLegend" property from the webmap.

The reason why I think this may be useful is because I have had to add multiple layers of the same feature class just for symbology purposes. I would just want the main layer to show and not all the other ones.

Robert,

Do you find this same issue or am I just doing something wrong?

Stan,

OK, I will begin on this enhancement and make sure I warn users in the settings dialog that it will remove the layer from the Layer List Widget and the Legend Widget.

Stan,

I do not find the same issue. When in AGOL I can go to one of my web maps and choose hide in legend and it does not appear in the Legend Widget in WAB.

Robert,

OK I looked at it some more and found that it only happens when I hide only a sub layer in a group. When I hide the top layer in the group it works as expected.

Here is a screen shot. When I hide the TOP layer it hides all. When I hide only the buffer layer then WAB does not respect that.

Robert,

This enhancement could be useful for me in certain situations but I am still looking for a solution to not showing the layer in the Legend widget while still including the layer in the Layer List widget .

For example, I have an Imagery tiled service which I would like my users to be able to turn off and on but I would rather not show this in the Legend widget as it is not needed to be shown there.

Your enhancements are greatly appreciated.

Regards,

Michael

Stan,

Yes sublayer hiding does not work. You may want to log and enhancement request with tech support.

Robert,

Hiding certain layers and sublayers from the layer list and the legend is just what I need. Right now using the local layer widget with a custom print template service the legend on the map is too cluttered. Are you still working on this enhancement or is it available since this was a couple months ago. Thanks!

Chad,

Unfortunately I have not had any time to invest in enhancements for the Local Layer widget. It is on a long list of things to do when I get free time.

Can I reprise this thread? I am having similar issues with a layer showing up in the legend of the print export from a WAB custom app, even though in the web map it's based on this layer is hidden in the legend. It does not show up in the legend of the web map, or in the legend widget in the app, but prints in the layout just the same. As said above it seems like the print service is not honoring the setting in the web map. Thoughts?

Cob,

I have not seen this as I have not used a workflow that encounters this. Have you reported this to esri tech support?
